Kernel crashes with ipsec connection over ppp
Description of problem:
I get kernel crashes when I set up an ipsec connection over ppp on a Huawei E220
HSDPA USB modem in the Fedora 9 beta. If I try to copy a large file over the
ipsec connection the machine hangs completely within a few seconds with the caps
lock and scroll lock lights blinking. I have an ipsec.conf file that looks like
this, somewhat censored:
If I set up an identical ipsec connection on an ethernet interface instead it
works without problems, and non-ipsec traffic on the ppp connection doesn't
cause any problems.
I have seen a few different kernel panic messages, attaching a file with three
Version-Release number of selected component (if applicable):
Crashes within a few seconds every time.
Steps to Reproduce:
1. Set up ipsec connection over ppp connection over HSDPA USB modem.
2. Copy a large file over the connection using scp.
No kernel crash.

Sample panic messages.
Changing version to '9' as part of upcoming Fedora 9 GA.
More information and reason for this action is here:
net/ipv4/netfilter/nf_conntrack_l3proto_ipv4.c:ipv4_conntrack_help(), line 131
return helper->help(skb, skb_network_offset(skb) + ip_hdrlen(skb),
helper contains a bad address: 0xffff810000000100
Is this still reproducible with the latest kernel? Thanks!
Seems to be fixed. I can't reproduce with neither kernel-188.8.131.52-73.fc9.x86_64 nor kernel-184.108.40.206-159.fc10.x86_64.
